据我所知,XStream 无法处理 XML 注释。
这是另一种方法,它使用 LexicalHandler API:
import org.xml.sax.*;
import org.xml.sax.ext.*;
import org.xml.sax.helpers.*;
import java.io.IOException;
public class ReadXMLFile implements LexicalHandler {
public void startDTD(String name, String publicId, String systemId)
throws SAXException {
}
public void endDTD() throws SAXException {
}
public void startEntity(String name) throws SAXException {
}
public void endEntity(String name) throws SAXException {
}
public void startCDATA() throws SAXException {
}
public void endCDATA() throws SAXException {
}
public void comment(char[] text, int start, int length)
throws SAXException {
System.out.println("Comment: " + new String(text, start, length));
}
public static void main(String[] args) {
// set up the parser
XMLReader parser;
try {
parser = XMLReaderFactory.createXMLReader();
} catch (SAXException ex1) {
try {
parser = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
} catch (SAXException ex2) {
return;
}
}
try {
parser.setProperty("http://xml.org/sax/properties/lexical-handler",new ReadXMLFile()
);
} catch (SAXNotRecognizedException e) {
System.out.println(e.getMessage());
return;
} catch (SAXNotSupportedException e) {
System.out.println(e.getMessage());
return;
}
try {
parser.parse("xmlfile.xml"); // <---- Path to XML file
} catch (SAXParseException e) { // well-formedness error
System.out.println(e.getMessage());
} catch (SAXException e) {
System.out.println(e.getMessage());
} catch (IOException e) {
}
}
}
